7 Claims.

invention is to provide a efflcient machine in which the elevator 'frame and a derrick frame therefor, are mounted on a chassis and may be supported in lowered idle positions when the machine is to be moved from place to place.

Another object is to provide the chassis frame with an upstanding stop frame which aids in its lowered idle when the latter occupies its vertical operative position.

A further object is to provide a, novel construction for mounting the elevator on the chassis frame and transmitting Figure 1 is a side elevation showing the elevator frame and the derrick frame in their lowered inoperative positions.

The general construction shown in the drawings, may be considered as preferred, and while that construction will be rather specifically described, it is to be understood that variations may be made within the scope of the invention as claimed.

A chassis frame If) is shown mounted upon wheels ii and having a tongue l2, said chassisframe having longitudinal side bars IS. A transverse cylindrical bar l4 preferably formed from a piece of pipe extends from one of the side bars l3 t the other at the rearends' of said side bars, and projects outwardly beyond these bars. The bar l4 preferably extends snugly through openings in the bars I3 and is suitably secured Two standards iii are supported by the transverse bar l4, said standards being spaced inwardly from the side bars l3 of the chassis frame in, the lower ends of said standards having openings through which said bar It extends. A transverse top bar it is secured to the upper ends of the standards l and has its driving power thereto. v

' frame which includes the top bar means of inclined ward movements of these bars.

.sitions, one of which is ends I! projected outwardly beyond said standards. The standards l5 are also connectedby a lower bar 18 and crossed brace bars l9, and said standards are braced to the chassis frame Ill by. braces 20. The elements l5, l8, etc., thus constitute a rigid upstanding frame disposed in a vertical transverse plane and performing functions hereinafter set forth.

A derrick frame 2| is provided, said derrick frame including longitudinal side bars 22 and longitudinal brace bars 23, the upper ends of said brace bars being secured at 24 to said side bars 22. These side bars are pivotally mounted at their lower ends upon the transverse bar l4- and are located between the standards l5 and the chassis frame side bars l3, and the brace bars 23 are pivotallly mounted upon the projecting ends of said bar l4, said bars 22 and 23 preferably having openings through which said bar 14 passes. Each brace bar 23 is connected at its lower end with the adjacent side bar 22, by a strap 25 to prevent relative inward or out- The upper end of each side bar 22 carries a sheave 26 for a purpose to appear.

An elevator frame 21 is pivotally mounted upon rigid posts 28 which rise from the front end of the chassis frame l0 and are braced thereto by suitable braces 29. This elevator frame is swingable from the lowered idle position shown in Fig. 1 to any of various inclined operative poshown in Fig. 2. When the frame 27 occupies its lowered position, it rests solidly upon the top bar l6 which is secured to the standards Hi. This elevator frame is provided side bars 22 of the derrick frame 2| rest when said derrick frame is in the lowered idle position shown in Fig. 1. When this derrick frame occupies its raised operative position, however, as seen in Fig. 2, its side bars 22 rest solidly against the projecting ends 11 of the top bar I6. It will thus be seen that the vertical transverse l6, performs a twofold function of aiding in supporting the elevator frame 21 when this latter frame is lowered, and stabilizing the derrick frame 2| when this derrick frame occupies its raised operative position. The upstanding stop frame also helps to take off side thrusts and it acts as a support for the winding drums or winches hereinafter described.

Two cables 3| are secured at 32 to the upper portion of the elevator frame 21, said cables being trained around the sheaves 26 and being with lateral stops 30 upon which the verse bars 41.

wound upon two winches at on a transverse shaft ll mounted in appropriate bearings on the standards ll. Any suitable provision may be made for rotating the shaft 34 to drive the winches a. For illustrative purposes, a worm gear I! is shown on theshaft It and meshing with a worm It on a hand-rotated shaft 81. When the frames II and ll are lowered as in Fig. 1. winding of the cables ii on the winches it will first eifect upward swinging of frame 2i until it solidly abuts the ends ll of the top bar it, and will then elevate frame 21 as required. By paying out the cables 3i from the winches, both frames may be lowered by gravity.

The frame 21 of the elevator includes paralle side bars 88, the lowerend portions of which are pivotally mounted upon a tubular bar 3| which is suitably secured to the posts 2.. A shaft-ll is rotatably mounted in the tubular bar II and projects beyond the ends thereof. One end of shaft 40 is connected by a chain and sprocket .or other drive II with one of the sprocket shafts 42 of the endless elevator. The other end of shaft '48 is provided with a pulley 43 driven by a belt 44 from a gas engine or the like 45 mounted on the chassis frame II. A suitable clutch (not shown) may be employed to stop or start the shaft 2 whenever required.

At points near their lower ends, the side bars 3! of the elevator frame 21 are connected by a transverse bar It (Figs. 3 and and said side bars are similarly connected at their upper ends. At intervals between their ends, these side bars have their lowerportions connected by trans- Secured to the various transverse bars, is a suitably slatted bottom ll to slidably support the bales or the like to be elevated, one bale being illustrated in dotted lines at 48 in Fig. 5. Above the floor 48, there are two rails 50 which are secured to the inner sides of the side bars 38, the upper edges of said rails being downwardly spaced a slight extent from the upper edges of said side bars. Two conveyor chains II which are engaged with the sprocket shafts of the elevator frame 21, have their upper reaches disposed upon the rails SI, and said chains are connected at widely spaced intervals, by means of transverse bale-pushing bars 52. These bars 52 are thus held su'fiiciently far above the floor 48 to prevent them from possibly riding under the rounded lower corners of the bales being elevated. These bales are simply dropped onto the fioor 48 between the guide boards 53, and each bale thus deposited is pushed upwardly along the floor 48 by the next pusher bar 52 to arrive. The bales can thus be elevated with much less strain on the endless driven elevator means than if they were actually carried by the latter.

It will be seen from the foregoing that the machine is comparatively simple and inexpensive, that it may be readily drawn from place to place, may be quickly and easily conditioned for use,

and may be conveniently employed in rapidly ele-.

vating bales, for example, for storage.

While excellent results are obtainable from the general construction shown and described, attention is again invited to the possibility of making variations within the scope of the invention as claimed.
